I went digging in CVS HEAD for 'checksum', and it wasn't clear to me if
this was end-to-end (from file write all the way to disk), or just an
option for network RPC's.
Is there some design or architecture document on the checksumming? All I
could find was some references to the kerberos5 RPC checksums.
